Eco-Kupplung (Eco-Clutch)

MEILLER Eco-Kupplung®

Operating efficiency for engine-driven PTO

The MEILLER Eco-Kupplung® (eco clutch) is the energy saving alternative to engine-driven fixed and variable displacement pumps. The eco clutch allows you to activate and deactivate the hydraulic system when needed. This considerably reduces energy consumption.

The eco clutch also allows the hydraulic system to be activated while travelling, facilitating manoeuvring and moving off. This ensures smooth working operation that saves time. The eco clutch is ideal for tippers, skip handlers and hooklifts*.

Your benefits:

  • Maximum availability of hydraulic system, even when the vehicle is moving
  • No additional energy consumption when the hydraulic system is deactivated
  • Reduced CO₂ emissions and mileage
  • For skip handler: Exact synchronisation of telescopic arms

This is how it works

Operating efficiency for engine-driven PTO

Faciliating flexible activation, the MEILLER Eco-Kupplung ® is located between the engine-driven PTO and the hydraulic pump.

  1. The operator activates the hydraulic system using the PTO switch and the pneumatics activate the partial-load switchable clutch.
  2. The clutch accelerates the pump and connects it to the engine output shaft.
  3. The hydraulic functions are available where the clutch is fully engaged.
  4. Following use, the driver deactivates the system again using the PTO switch in the cab.
